Calculate .m4s segment file suffix in HTML5 video streaming when user seeks to another time

心已入冬 提交于 2019-12-04 00:46:26
I have created fixed length segments for a long MP4 video using Mp4Box. Mp4Box creates a meta info file mv_init.mp4 and segments like mv_1.m4s , mv_2.m4s , … I stream the video using HTML5 Media Source Extensions and the streaming is working properly. The problem is that I am unable to utilize time seeking feature of my HTML5 player . When a user uses the seekbar to seek to another time point, I need to fetch the correct segment file ( mv_{number}.m4s ) for that currentTime . For example: video duration: 2 hours segment size: 10 seconds user seeks to time: 25 minutes 25 minutes = 25 × 60

Split fragmented MP4 into multiple MP4 files

问题 We're trying to parse the fragments of an fMP4 file into separate independent MP4s. Can anyone help point us in the right direction to do this, or is there any open source code that exists that we could leverage? 回答1: I think MP4Box might be what you are looking for. It's open source, so you can have a look at the code if you want to know how this can be done. It can also be used as command line tools, e.g. as described in this blog post (skip to the "Segmenting" section): MP4Box -dash 4000

Create MPEG-DASH Initialization segment

*爱你&永不变心* 提交于 2019-11-30 14:06:19
I am looking to convert between HLS and MPEG Dash. I do not access to the original fully concatenated video file, only the individual HLS segments. In doing this transformation to MPEG Dash I need to supply an initialziation segment for the Dash manifest .mpd file. My questions are: What is the structure of a Dash video initialization segment? How can I generate/create one without the need for the original full file? Perhaps a solution would involve getting MP4Box to convert the '.ts' HLS segments to Dash '.m4s' segments which are self initializing, but I am unsure how to go about this this?

I'm looking for a MPEG DASH downloader and youtube_dl just hit on me. Given a .mpd URL , is that possible to use youtube_dl to download all media segments then? iuridiniz To download all video and audio segments and mux them into a single file, call youtube-dl thus: youtube-dl -f bestvideo+bestaudio http://URL/TO/manifest.mpd The option -f <id1>[,<id2>]... is used to select which stream (or streams) of segments to save. The -f bestvideo+bestaudio in this example makes youtube-dl save only the best video and audio streams. See format selection syntax for details and more advanced format

Low Latency DASH Nginx RTMP

I use arut nginx-rtmp-module ( https://github.com/arut/nginx-rtmp-module ) on the media server, then I tried to stream using FFmpeg to the dash application, then I test the stream by playing it using VLC. And it waits around 30secs to start playing, and it plays from the beginning, not the current timestamp. This is my current config on the RTMP block rtmp { server { listen 1935; application live { live on; exec ffmpeg -re -i rtmp://localhost:1935/live/$name -c:a libfdk_aac -b:a 32k -c:v libx264 -b:v 128K -f flv rtmp://localhost:1935/hls/$name_low -c:a libfdk_aac -b:a 64k -c:v libx264 -b:v
